In 1970 a lottery was held to determine who would be drafted (and sent to Vietnam). For each date of the year, a ball was put into an urn. For instance, January 1 was number 305 and February 14 was number 4. Thus a person born on February 14 would be drafted before a person born on January 1. The file P3_43.XLS contains the “draft number” for each date for the 1970 and 1971 lotteries. Do you notice anything unusual about the results of either lottery? What do you think might have caused this result?
